CC -!- FUNCTION: Part of the Sec protein translocase complex. Interacts with
CC the SecYEG preprotein conducting channel. Has a central role in
CC coupling the hydrolysis of ATP to the transfer of proteins into and
CC across the cell membrane, serving both as a receptor for the
CC preprotein-SecB complex and as an ATP-driven molecular motor driving
CC the stepwise translocation of polypeptide chains across the membrane.
CC {ECO:0000256|HAMAP-Rule:MF_01382}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O + cellular proteinSide 1 = ADP + phosphate +
CC cellular proteinSide 2.; EC=7.4.2.8; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_01382};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|ARBA:ARBA00001947};
CC -!- SUBUNIT: Monomer and homodimer. Part of the essential Sec protein
CC translocation apparatus which comprises SecA, SecYEG and auxiliary
CC proteins SecDF-YajC and YidC. {ECO:0000256|HAMAP-Rule:MF_01382}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000256|HAMAP-
CC Rule:MF_01382}; Peripheral membrane protein {ECO:0000256|HAMAP-
CC Rule:MF_01382}; Cytoplasmic side {ECO:0000256|HAMAP-Rule:MF_01382}.
CC Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01382}. Note=Distribution is 50-
CC 50. {ECO:0000256|HAMAP-Rule:MF_01382}.
CC -!- SIMILARITY: Belongs to the SecA family. {ECO:0000256|ARBA:ARBA00007650,
CC ECO:0000256|HAMAP-Rule:MF_01382, ECO:0000256|RuleBase:RU003874}.
